Question about ComRegisterFunctionAttribute...

Hi all,

I seem to have a problem with ComRegisterFunctionAttribute attribute. Here
is a bit of sample code:

// Start of sample --------------------
// --------------------
// Sample.cs
// --------------------
using System;
using System.Collections.Generic;
using System.Text;
using System.Runtime.InteropServices;
using System.Windows.Forms;

namespace SampleLib
{
    public static class Guids
    {
        public const string CLSID_TestGuid =
            "33DE01D3-DC04-4198-AE5D-58B1A36FC122";
    }

    [Guid ( Guids.CLSID_TestGuid ), ProgId ( "SampleLib.SampleClass" )]
    [ClassInterface ( ClassInterfaceType.AutoDual )]
    [ComVisible ( true )]
    public class SampleClass
    {
        public void SomeFunc ()
        {
            MessageBox.Show ( "Something" );
        }
    }

    public static class Helper
    {
        [ComRegisterFunctionAttribute]
        public static void RegServer ( Type oType )
        {
            MessageBox.Show ( "Register" );
        }

        [ComUnregisterFunctionAttribute]
        public static void UnregServer ( Type oType )
        {
            MessageBox.Show ( "Unregister" );
        }
    }
}

// --------------------
// AssemblyInfo.cs
// --------------------
using System.Reflection;
using System.Runtime.CompilerServices;
using System.Runtime.InteropServices;
using System.Security.Permissions;

[assembly: AssemblyTitle ( "SampleLib" )]
[assembly: AssemblyDescription ( "" )]
[assembly: AssemblyConfiguration ( "" )]
[assembly: AssemblyCompany ( "" )]
[assembly: AssemblyProduct ( "SampleLib" )]
[assembly: AssemblyCopyright ( "Copyright C  2008" )]
[assembly: AssemblyTrademark ( "" )]
[assembly: AssemblyCulture ( "" )]
[assembly: RegistryPermissionAttribute ( SecurityAction.RequestMinimum,
        ViewAndModify = "HKEY_LOCAL_MACHINE" )]

[assembly: ComVisible ( false )]
[assembly: Guid ( "86077dae-29ae-4905-855b-798aaa7be210" )]
[assembly: AssemblyVersion ( "1.0.0.0" )]
[assembly: AssemblyFileVersion ( "1.0.0.0" )]
// End of sample --------------------

The build output is a single DLL, SampleLib.dll.

It seems that the above code builds without any errors but when I try to
register the resulting DLL using regasm.exe, the RegServer and/or
UnregServer function is never called. According to the documentation, these
functions can be public or private (or internal), but they must be static
and take a single Type parameter to be called during registration for COM.

Is there anything I need to do to make this working? I'm using .Net 2.0 with
SP1 and I have this same behavior on several computers. Any advice would be
greatly appreciated.

Thanks,
Gyorgy Bozoki
